Project Explanation with Architecture

Various modern tools that come under Hadoop ecosystem

Here we shall discuss a little about the different components of the Hadoop ecosystem. First let us start with what is meant by Hadoop ecosystem. HDFS and MapReduce are the core components of Hadoop framework on which Big Data is stored and processed in a distributed manner. Hadoop ecosystem refers to a set of tools that help in storage and processing of Big Data. Another important fact is that the members of the Hadoop ecosystem are always increasing. What is happening is that all the tools that are based on distributed technology are getting integrated with Hadoop framework with time; this way the possible use cases increase substantially.

The first one that needs to be discussed here is Pig: it is a tool that used cryptic statements to process the data. It would take an enormous amount of time and effort to write multiple jobs in languages like Java or Python. The pig is a relatively simple data flow language that cuts down on development time and efforts. Typically it was designed for data scientists who have less time and programming skills.

Hive provides SQL-like language tool that runs on top of MapReduce. Pig and Hive were developed at different places; Pig was developed by Yahoo and Hive by FaceBook but with the same idea in mind. Both of these tools were designed to aid data scientists with poor programming skills to process the data. So, observe that both Pig and Hive are above MapReduce layer; the code written in Pig or Hive gets converted to MapReduce jobs that are then run on HDFS.

To facilitate the movement of data into or out of Hadoop, the tools Flume and Scoop were created. Scoop helps in moving the data from a relational database and Flume is used to ingest the data as it is generated by an external source. Then there are tools like Impala, which is used for low-latency queries. HBase is another tool that provides features like a real-time database for retrieving the data from HDFS, and there are many other similar tools that provide different functionalities as well.

The biggest problem with all these tools is that they have been developed independently and parallel by various organizations. For example, when Yahoo came up with Pig, FaceBook came up with Hive, and they made the tools open source to be used by everybody. So, what has happened is there are a lot of compatibility issues between the two tools. This is where Cloudera and Hortonworks come into the picture, and they score points. They also package all the open source components and add their flavor and release their versions of packages. Hence, these packages released by them have all the ecosystem components, and they are compatible as well. Hence, the business model is to keep the products open source and free of charge and charge for the services.


  1. Hi,
    I am looking for Hadoop training institutes.
    I want to learn the hadoop course in evening batches. Did any Evening batch is running right now?Call me over the phone with all details.
